Hello guys,

After I upgrade my php version from 5.3 to 5.5 many errors has appeared in my sites.

For example:

Line 769 code:

<h3>          <a href="http://domain.com/page"><span>Name List</span></a>          </h3>               <ul>                  <?php                              global $wpdb;                       $postTab = $wpdb->prefix."posts";                   $postMeta = $wpdb->prefix."postmeta";                   global $post;        ?>                          <?php  query_posts( 'post_type=model&portfolio_cat&Featured&orderby=title&order=ASC&paged=' . $paged);               while ( have_posts() ) : the_post();                   $mrpostParent =$post->ID;                                       $ttFGQue =mysql_query("select * from $postTab as a,$postMeta as b where a.ID=b.post_id and a.post_type='freegallery' and a.post_status='publish' and             ( b.meta_key='mr_freeGalleryModel' or b.meta_key='mr_freeGalleryModel_2') and b.meta_value='$mrpostParent'");                                                            if($ttFGQue && mysql_num_rows($ttFGQue)>0)        {                                                        $totalFg = mysql_num_rows($ttFGQue);        }                                                     else{                                                       $totalFg="0";                                                        }                                     ?>                                                     <li>                                                   <a href="<?php the_permalink(); ?>"><?php the_title() ?> (<?php echo $totalFg; ?>)</a>                      </li>                       <?php  endwhile;         ?>              </ul>

Line 97 code:

$ttFVQue =mysql_query("select * from $postTab where post_type='freevideo' and post_status='publish' and post_parent='$mrpostParent'");    

PHP:

Line 95 code:

I really appreciate it if someone can help me

Thank you!!

 

Check your mysql_connect settings. Currently you're trying to connect to the database without a username

 

Also to add, the original mysql functions are deprecated. If you have the ability to, switching to another database method like mysqli or PDO is a good idea, and likely safer.

 

Do you have root access to your server? Or are you using shared hosting?
